If two levels of prevedence (ordinary and weak) are not enough, why will
three levels be so much better?
If you use a signed fractional or even floating-point precedence value,
you have a lot more space to accomodate afterthoughts - above, below,
and in-between in precedence to existing values.
Even better, you could use symbolic tags, and have the linker script
assign precedence values to these tags.
